Magnesium oxide nano powders were prepared by precipitation method using anhydrous sodium carbonate and magnesium chloride hexahydrate as raw materials, and the influence of chloride ions in the synthesis of the powders was investigated. It was shown that the precipitation process with the addition of chloride ions could change the phase composition of the precursors, […]

The high-performance requirements of special cements put forward more stringent control targets for production process conditions, raw material selection, process quality monitoring, testing methods and other aspects. In view of the individual technical needs of the project, the control range of special cement indexes can be adjusted appropriately to provide better control. Take magnesium oxide

Modified magnesium hydroxide nanoparticles with 98% yield were synthesized by an easy-to-industrialize liquid-phase precipitation method with the synergistic effect of sodium dodecyl sulfate (SDS) and sodium polyacrylate (PA-Na) compound modifiers. The optimum amount of modifier was determined by the settling volume experiment to be 0.2% (mass fraction of the compound modifier to the synthesized sample),

The present invention discloses the method of producing alkaline magnesium carbonate. Crude hydrazine preparation step, from the reaction of urea liquid and sodium hypochlorite in the reactor to produce hydrazine hydrate, the temperature of crude hydrazine in the reactor at 100 degrees -110 degrees, the by-products include sodium chloride and sodium carbonate; distillation step, without

The pollution caused by the emission of sulfur dioxide and nitrogen oxides in China is becoming more and more serious, and the national efforts to control air pollution are gradually increasing. It is necessary and urgent to research and develop economic, efficient and simple flue gas desulfurization and denitrification technology. The chemically prepared magnesium oxide

Magnesia ceramic is a typical new type of ceramic and also a traditional refractory. Magnesium oxide itself has strong corrosion resistance to alkaline metal solutions. The prepared magnesium oxide ceramic crucible has excellent chemical properties and stability against metal corrosion, and has no effect on magnesium, nickel, uranium, aluminum, molybdenum, etc. Magnesium oxide ceramics can

河北梅西生物有限公司表示，氧化镁的用途非常广泛。除了较高纯度和较低重金属含量的关键特性外，医用和食品级氧化镁也有非常不同的应用。医用级氧化镁主要用作药用辅料等领域。 医药级氧化镁可用作颠茄片。它的作用是中和胃酸。其原理是中和酸碱。其抗酸作用比碳酸氢钠强、慢、长。它不产生二氧化碳。与胃酸反应生成氯化镁，释放镁离子，刺激肠道蠕动，具有通便作用。还可用作动物药、动物土霉素等。除上述用途外，还可用于B12发酵。 医药级氧化镁重金属含量低，氧化镁含量高，杂质含量低。河北梅西生物有限公司严格按照国家标准进行检测。从原材料到生产过程再到成品，产品的每个环节都必须严格按照GMP要求进行。合格产品方可入库，每次出厂前，必须严格按照国家标准要求重新检测各项指标。

Hebei Messi Biology Co., Ltd. pointed out that at present, high-purity nano magnesium oxide is widely used in battery and electronic fields, among which the magnetic material of magnesium oxide is an indicator that customers are more concerned about. It is found that the polycrystalline magnesium oxide has weak ferromagnetism when the macro crystal is

Granular magnesium oxide and powdery magnesium oxide look just different in appearance and shape. They are both made of magnesium oxide as raw material. However, due to the different advantages and disadvantages of these two kinds of magnesium oxide, their application sites are also different. In the process of tablet pressing, the material is not

The high-purity MgO samples were prepared by carbonation method with the addition of sodium oxalate to remove calcium before the pyrolysis of heavy Mg water. The optimized conditions were obtained by investigating the effects of carbonation concentration (the ratio of solid mass to water mass in the slurry before carbonation), sodium oxalate dosage and aging
